. It is one of the objectsofthis invention to providean improved sheet conveyer adapted to receive sheets of material in a double row, `1n which novel means `1s employed for automatically shifting saidsheets into single file as they are being conveyed. The saidconveyer 1s particularly adapted for use in connection with a unitary box making machine such as i's described in the application af Emery L. Walker and Arthur lV. Werner,

` A further object of this invention'is to provide an improved sheet conveyer of the type described, in which` means is provided `for automatically shunting sheets which have.

doubled up on one anotherY in passingV along the conveyer so that said doubled up sheetsv will not interfere with subsequent operations of the box making machine.

as set forth inthe claims, and all equivalents i In the accompanying drawings, illustrating one complete embodiment ofthe preferred form of the invention, in which the same reference numerals designate the same parts in. allV of the views:

Figs. k1 and 2 illustrate a-plan view of the conveyer, a portion of a boXomaking machine Y ,4-4 of Fig. 2;

ltaken on line k being shown in connection therewith;

Fig. 3 shows a side elevation of the portion of the conveyer shown in Fig. 1;

Fig. 4 is a sectional view taken `on line Fig. 5 is an enlarged sectional detail view 5 of Fig. 1; and

Fig. 6 is an enlargedsectional detail view taken on line 6-6 of Fig. 1.

Referring to the drawings, the numeral 10 designates a unit of a boxmaking machine having a drive shaft 11 journaledl there- Y through. rlhe said drive shaft carries on one end loosely mounted sprocket wheels 12 and 13 which are adapted to be selectively engaged by a clutch member 14. On its otherv end, the shaft 11 carries -a rigidly mounted 1929. seran. No. 381,470.V

gear 15 which meshes with a gear 16 rigidly mounted onta shaft 17. Onthe-other end of the shaft 17 Vis. arigidly mounted gear 18 which drives a gear 19 rigidly mounted on a shaft '20. The latter shaft carries cutting disks 21 which are adapted to sever a sheet of material extending the entire width of the unitglO intotwo sections and totrim the outer edges of Samet-o theproper size for forming a container.

A rod 22, atthe outer end of the unit 10 carries arms 23 which are provided with rollers 24. `Teights 25, on said arms, hold saidv rollers in contact with the sheets vas they are fed from the unit 10 to the platform 26 ,of a 'conveyer' frame 27. .Y f j J Ournaled in the end of the conveyer frame 27 adjacent the unit 10 is ashaft 28 carrying rigidly mountedl rollers 29. Another shaft 30 carries rigidly mounted rollers 31v which y project ythrough openings 32 inthe top por- With the above and other objects in view,

the. invention consists of the improved sheet conveyer, and all its arts and combinations,y

tion26`ofthe frame. Endless belts 33T for conveying thev sheets, connect .said rollers.

Also rigidly mounted on the shaft 28 are Y The sprocket Wheel '35 is connected by an Y endless chain 41 which moves in a slot 242,

with a sprocket 43 ona shaft 44 (see AThe-said chain also carries lugs 45.

Journale-d .transversely below Van interme' diate portion of the conveyer frame is a shaft 46 having sprocket wheels v47 and 48 rigidly mounted thereon. The latter are connected by endless chains 49 and V50 with the sprocket wheels 13 and 12 respectively on the unitilO.'

'As the sprockets 47 and 48 'areo'f difere'nt sizes, the shaft 11 on the unit .10 may be driven at two different speeds, according to` which of the sprockets 12 and 13 is engaged bythe clutch l14.

The shaft 46 also carries a rigidly mounted Y bevel gear 51 which ymeshes with a bevelfgear 52 on ashaft 53 journaledbelow thevvframe.

z The shaft 53 carries three .rigidlymountedr sprocket wheels 54.` Mounted on shaftA above the shaft 53 are three other sprocket v6,5 `in `the conveyer platform .26., `and to rest upongliidingfplates 66, ,as shown in y When double sheets come out of the unit 10, the sheets carried by the chai-n 'aremoved to the portion of the frame having the slots 65, within which .the lugsjfrfaretravelling. Here the sheets are engaged by said flugs, yand are .moved in a direction at right angles to their former direction of travel, :bef't-ween `the sheets being carried by the chain Thus, the sheets which come out-of the un'it 10 in pairs,-are operated-onby the chains 63 so that they travel in single iile.

Brackets 67-onopposite sidesvof the frame have a arod journaled -therein which carries rigid arms 69. |Pu'll'roller-s170 are valso `journaled between the brackets -v67 and Asaid rollers '-a-re sdriven by an endless chain 70 vconnecting afsproc'ket wheel 71 withasprocket Y "711'l onfthe shaft '46. A -platform72.extends fromthe brackets, parallel lto the frame `lout spaced `thereabove.

Extending from an end of lthe yrod 68 -is an arm 73 having apiston-'extending down-Y ftvardly therefrom, kThe said piston `Venters the core of a solenoid and pivoted thereto.

which is lwired toa conduit box 7 5 (see '6) 'The' said conduit box yis `'positioned "above a shaft76fthe latter being journaled.

"in abeari-ng 77. AOne end'of said shaft carries ka gear'78 which meshes with la gear 79 A'on afshaft 80. Thetlatter'shaft has asprock- 4 et -Wheel 81`whic`h is ldriven by the endless A'c'ha'inf50- Theo'ther-end of the shaft 76 carries a roller 82 below which Iis a roller wheel vr83 rigidly lmounted -on theshaft "80. 'The two rollers are normally held sufficiently far apart Ivto permit 'a single Vthickness of cardboard to pass therebetween. If, kthrough some faccident,-two sheets 4pass `between the rollers, the roller 82 will be raised up `to `close 'a switoh '84 below the conduit box 7 5. (This will cause the solenoid 74 -to be ener- !g'ized, thereby 'pulling down on the arm 73, `'causing the shaft 68 to be turned, 'and the :arms `69 to be moved downwardly so that their end Lportions enga-ge the top of the frame. "The sheets-of cardboard', instead of lyimoun'ted'sprocket `wheel 85 which isconfnectedby an endlessfc'hain 86 with'a sprocket wheel '-87 on-the drive shaft 880fa motor 89. A shaft 90 is lprovided with a rigidly mounted sprocket wheel 91 and with a gear 92 meshing with a gear 93 on the shaft 46. The sprocket 91 is connected by an endless chain 94 with a sprocket wheel 95 on the shaft 44.

In the opera-tion of the device,rthe sheets of material which have been severed into `two-.sections by the cutting disks 21 pass in a double row from the unit 10, beneath the rollers 24, onto the Aplatform 26. ,The said rollers, being weighted down y'by the weights 25., hold the sheets fiat upon the platform. The sheets are then engaged by the lugs 39 fon the :chain-B6 'and by the lugs 45 on the chain 41, and are conveyed in a double row. Then lthe sheets 4which are 'being moved by the chain 36 reach the portion of the :plat- `form which visV provided with the transversely extending vchains 63, the sheets :are lmoved in a direction 'at right angles to `t'heirfform'er Vdirection of travel, between lzthe Asheets which are being conveyed by-the chain 4l. Tl1us,fthe -con-veyer is adapted ito 'receive sheets in a double .row `and ito automatically shi-ft said vsheets into .single fiile so y"that'they may be fed in -the flatterV order :into a vsubsequent machine.

It is to be notedthat the-conve :er `chains 136 andV 41 and the 'shifting Ichains 63 :have interrelated driving mechanism, the latter being so larranged lthat .th'echains .63 will lbe driven ata Irelatively high speed,-and will 'be so timed with :relation to ithe c'hain41 as conveying material in -thesame direction in I a double frow, and em'iless'shifting Vmeans yon said platform engageable with `the material Ain one row only `for causing said two rows" to be combined Vinto-a single irow.
